Hello everyone, and welcome to another Friday Product Post here at SparkFun Electronics! This week, we have two new Qwiic Temperature Sensors for you in two form factors! Both of these boards feature the highly accurate STTS22H sensor from STMicroelectronics. These two boards are a great addition to the Qwiic Ecosystem and come in a Standard and Micro form-factor. Following that, we have an updated version of the classic SparkFun LiPo Fuel Gauge as well as a new SMA cable.

Even though our first 20th Anniversary Sale of the year is over, we have plenty of exciting products still on sale that you can take a closer look at on our Clearance page as well as the rest of our specials on our Sales page!

Okay, new product time!

The newest Environmental Sensor comes to Qwiic, twice!

The SparkFun STTS22H Temperature Sensor is a Qwiic-enabled breakout board based on the ultralow-power, high-accuracy, digital temperature sensor from ST Microelectronics and housed in our Standard and Micro Qwiic form factors. Thanks to its factory calibration the STTS22H offers high-end accuracy performance over the entire operating temperature range, reaching as low as ±0.5°C without requiring any further calibration at the application level.

SparkFun LiPo Fuel Gauge

SparkFun LiPo Fuel Gauge


The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect the relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.

When experimenting with GPS or RF it can be very handy to have the antenna on the top of your house or outside with a clear view of the sky while you stay in doors and warm at your keyboard. This 10m (33') SMA Interface Cable does a great job of connecting your receiver or radio to a distant antenna with as little RF loss as possible.

That's it for this week. As always, we can't wait to see what you make. Shoot us a tweet @sparkfun, or let us know on Instagram, Facebook or LinkedIn. Please be safe out there, be kind to one another! We'll be back with more new products next week so make sure to check back then. Happy hacking!

Never miss a new product!
